The accuracy and reduced cell count provided by structured meshes are nearly a prerequisite for ship resistance prediction for naval vessels because of free-surface effects and very high Reynolds numbers.

This paper provides CIMdata’s perspective on Computational Fluid Dynamics (CFD) analysis; the motivations for its use, its value and future, and the importance for making CFD available to all engineers earlier in the product design/development lifecycle.

With more processors being readily available on large
computing systems today, there have been many discussions involving the potential scalability of legacy codes/numerics concerning their ability to fully utilize large core count machines.

The prevailing thought and conclusion of those involved in the discussions were that legacy codes could not scale well on thousands of processors, let alone tens of thousands of processors.
